CHARLES H. COOLEY, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE PRATT 8s IVHITNEY COMPANY, OF SAME PLACE.

REGULATOR FOR GRAIN SCALES.

SPECIFICATION forming part of Letters Patent N o. 409,669, dated August 27, 1889.

Application filed October 15, 1888. Serial No. 288,160. (No modeli) To (tZZ whom it may concern.-

Be it known that 1, CHARLES II. COOLEY, a citizen of the United States, residing at llartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Regulators for Grain- Scales, of which the following is a specification.

This invention is in the nature of an improvement in the corresponding part of the regulator apparatus described in my application for Letters Patent of the United States, Serial No. 288,159, filed October 15, 1888.

In the drawings accompanying and forming a part of this specification, Figure 1 is a sectional elevation of those parts of a grain-scaleregulator apparatus which embody my present improvements. Figs. 2 and 3 are similar views further illustrating the construction and mode of operation of said improvements.

Similar characters designate like parts in all the figures.

In the drawings, the floor or platform supporting the grain-scale (not shown herein) is designated by F. The regulator-hopper P, lever L, counterbalance-weig]1t 92, and fixed conduit 93, are all supposed to be the same, or substantially so, as the respective parts in my aforesaid Letters Patent and to have the same functions and mode of operation.

It will be remembered that the grain-bucket of the automatic grain-scale discharges its loads of grain intermittently into the rcgula tor-hopper P, from whence the grain passes down through the opening N and through the connecting-pipe 9i and fixed conduit 93 into a normally oversupplied grain receiving chamber or apparatus below said conduit, and that since the grain-discharging capacity of the grain-scale is normally greater than the grain-receiving capacity of the said grain-receiving chamber the conduit 93 and pipe 94 are kept fully supplied with grain so long as the machinery is in operation. As the grain runs down and out of the hopper P, as indicated at 125 in Fig. 1, the weight 92 overbalances the hopper P, and this rises, as there shown. This movement extends the flaring upper end of connecting-pipe 94, leaving the clear space 150 outside of and around opening N and Within the outwardly-flaring upper end (1 of said flexible pipe, which upper end is secured at c c to the under side of hopper P at some distance from the opening N. On receiving its next load 'of grain, as indicated at 130 in Fig. 2, the loaded hopper P then overbalances the weight 92 and descends, as indicated in Fig. 3. In doing this, however, (the column of grain 1.80 usually having but a slow downward m otion,) the grain at 100, in Figs. 1 and 2, is forced outwardly and upwardly into the said space 150, as indicated at 170, Fig. 3, this operation being facilitated by the flexibility of the flaring part (Z of pipe 94, which quality allows said part to be bulged out, as there indicated, to permit a freer outward movement of the grain into said surrounding space. As the column 180 descends, the displaced grain at 170 runs down with the column and leaves the space 150 free, as in Fig. 1, ready for the next operation. of the regulator-hopper.

Having thus described my invention, I

The combination, in a regulator apparatus of the class described, of the vertically-mow able hopper, the fixed conduit below said hopper, and the flexible connecting-pipe having its upper end outwardly flaring and joined to said hopper around and above the dischargeopening, whereby there is provided a space around the opening in the hopper and within said flaring part, all substantially as described.
